Former Cuban dictator Fidel Castro is speaking out about President Obama’s trip to the communist nation. Castro, who hasn’t made a public appearance since July of 2015, was less than diplomatic in his assessment of the President’s visit.

“Listening to the words of the US president could give anyone a heart attack,” the 89-year old Cuban revolutionary said. “My modest suggestion is that he think and not try to theorize about Cuban politics.”

“Obama gave a speech in which he used the most syrupy words,” said Fidel, who handed over power to his brother Raul Castro in 2006. “Nobody has any illusion that the people of this noble and selfless country will surrender glory and rights and the spiritual wealth that has come through the development of education, science and culture.”

Despite his advanced age and questionable health, the former communist dictator remains defiant.

“I would also warn that we are capable of producing the food and material wealth we need with the labor and the intelligence of our people. We don’t need any gifts from the empire.”
